If filing a bug please include the following:

Nomad version

Nomad v0.10.1 (0d4e5d9)

Operating system and Environment details

Ubuntu 16.04.6 LTS on AWS
Nomad clusters federated between three AWS regions, us-east-1, us-west-2, eu-central-1

Issue

When connected to the Nomad UI with a cluster that is not the selected cluster, stopping a job in the selected cluster stops the job in the cluster local to the UI you are accessing instead.

Request targets the Nomad API local to the UI region without setting the region query param.

Reproduction steps

1. Access the Nomad UI from a datacenter endpoint (ie., http://nomad.us-east-1/ui/)
2. Change the region selector to a remote region (ie., eu-central-1)
3. Pick a job out of the list of running jobs
4. Click the stop button and confirm

Now the job will be stopped in us-east-1 but not eu-central-1.

Job file (if appropriate)

Stupid-simple job to test with. Deployed to each region.

job "sleeper" {
  datacenters = ["dc1"]
  type        = "system"
  priority    = 75

  group "app" {
    task "sleeper" {
      driver = "docker"

      config {
        image      = "alpine:latest"
        force_pull = true

        command = "/bin/sleep"

        args = [
          "3600",
        ]
      }

      resources {
        cpu    = 64
        memory = 64
      }
    }
  }
}

We are hitting this in 0.10.2 as well.
I believe this was solved in 0.12.1 by @DingoEatingFuzz. Can someone confirm if this is not planned to be backported?

[tgross]

This won't be backported to 0.10.2, sorry.
